Tips for Care

Keep your trees healthy with a planting site in full sun with at least six hours of direct sunlight a day. Although they are widely adaptable, you’ll get best performance in well-drained soil.

Ensure your tree has plenty of air circulation and room to spread out. You can prune to correct in late winter, but you’d hate to have to disrupt their astounding Elm form with size control pruning.

Better to choose a more compact variety in small lots. Use Valley Forge American Elm where you have enough room for these impressive shade trees.

No matter which disease-resistant Elm you choose, be sure to add a packet of Nature Hills Root Booster to your order. Follow the directions when planting.

Our nursery teams swear by this time-tested formula. Among the ingredients is mycorrhizal fungus, which works with your tree’s tiny feeder roots to encourage optimal access to water and soil nutrients.

We recommend giving it a medium amount of supplemental water. You’ll keep your tree stress-free and healthy. Please, protect your investment, especially in times of drought.

Mulch is another helpful way to support your tree. Add a three-inch layer of mulch over the root system, then pull it back six inches from around the trunk.

Native trees give us so much, and these disease-resistant trees perform beautifully in the landscape.
